TV Guide reports that on the fourth episode of Season 21, Nick is caught off-guard when he witnesses a fierce side of one timid bachelorette. The contestant, while bonding with Nick’s family, decides to open up about a previous heartbreak. Meanwhile, another bachelorette faces up to Nick and talks to him about his behaviour with another woman. The Jan. 23 episode also features country singer Chris Lane, who performs during a romantic dinner in a one-on-one date.

ABC posted a sneak peek for Monday’s episode on its official YouTube page, showing the remaining contestants are brought to Nick’s hometown to meet his family. Some ladies find themselves having to do some farm work to impress the 36-year-old software sales executive. Meanwhile, every single person in “The Bachelor” house is questioning why Corinne is here.

The 24-year-old business owner finds herself at the centre of drama, and a heated argument occurs between her and Taylor. When the mental health counselor doubts Corinne’s maturity, the blonde beauty argues that she has a multi-million dollar company. “The Bachelor” viewers would remember that last week, Corinne got the flak when she decided to be extremely seductive during the cocktail party. She was also absent at the rose ceremony after oversleeping.

Monday’s teaser also shows Raven Gates, who says she’s falling in love with Nick. Spoilers hint that she and Nick will spend some fun and romantic moments while skating. Reality Steve reports that Danielle Lombard will also have a one-on-one date with Nick at the Steaming Cup, before going to a Chris Lane concert. Their date becomes more exciting when they bump into Nick’s ex-girlfriend named Amber Allan, who’s married with two kids. Both Raven and Danielle will get roses, while Kristina Schulman receives the group date rose.
